Perfect validity means that a measure measures exactly what it is supposed to measure. Perfect reliability means that a measure is consistent over time and across different observers. If a measure is perfectly valid, then it must also be perfectly reliable, because if it is not consistent, then it cannot be measuring what it is supposed to measure.
